Jonas et al. (1998) used the Hartebeesthoek Radio Astronomy Observatory (HartRAO) telescope to map 67% of the sky at 2326 MHz with an angular resolution (HPBW) of 20 arcminutes and rms pointing accuracy of 1.2 arcminute. All survey observations were made in linear polarization (E-vector east–west). The sky region covered is -83 < dec < 13 for 0 h < RA < 12 h and -83 < dec < 32 for 12 h < RA < 24 h. They estimated that the uncertainty in the temperature scale is less than 5 per cent, and that the error in the absolute zero level is better than 80 mK TFB in any direction.
Platania et al. (2003) applied a destriping algorithm to the portion of the map at dec < 13, and produced Cartesian and HEALPix versions of the original map and the destriped map. All of the maps are available from CDS. LAMBDA hosts copies of the HEALPix maps obtained from CDS.
